Abstract

Rice is one of the staple grains in China and has a strong relationship with annual accumulation temperature which has a potential effect on rice planting area. This study utilizes a model called SPAM (Spatial Allocation Model) to detect the rice spatial distribution change during the 1981-2010 under the climate change in the Northeast China Plain. The result shows that climate change plays an important role in the rice spatial distribution. The tendency of rice spatial distribution has an obvious feature which has extended to north dramatically in the Northeast China Plain. Annual accumulation temperature is the main factor to rice planting in the higher latitude region.
